Mmm, Blender had a lot of problems having to reverse FBX from autodesk, which AFAIK is or was a de-facto standard. About open standards, I kinda hate xml, so I didn't like Collada much. I'm looking forward for knowing more about glTF[1]. Thankfully Blender 2.8 had the official add-on from the beginning.
